The invention relates to a screw rotor and a method for manufacturing such a screw rotor. The screw rotor is characterized in that the screw rotor (1) is made out of polymer, wherein the screw rotor (1) consists of a shaft (2) with a rotor body (3) on it, wherein the polymer of the shaft (2) is reinforced with fibers (4), wherein the shaft (2) features elements (5a, 5b) that engage the rotor body(3) or corresponding elements (5c) on the rotor body (3), such that the elements (5a, 5b, 5c) prevent an axial and/or rotational movement of the shaft (2) with respect to the rotor body (3). 本发明涉及螺杆转子及制造螺杆转子的方法。一种螺杆转子，其特征在于，螺杆转子(1)由聚合物制成，螺杆转子(1)由轴(2)和在轴(2)上的转子主体(3)组成，轴(2)的聚合物用纤维(4)增强，轴(2)具有与转子主体(3)接合或与转子主体(3)上的相应元件(5c)接合的元件(5a，5b)，从而这些元件(5a，5b，5c)防止轴(2)相对于转子主体(3)轴向运动和/或旋转运动。
